SELF-REGULATING AND FIXED-RESISTANCE ELECTRIC FLOOR HEATING
Self-regulating heating, unlike the commonly used fixed-resistance cables, automatically adjusts the heating power along the length of the cable to the ambient temperature by responding to external heat sources. Due to its design using a polymer self-regulating element:
- SAFE: there is no possibility of heating above the marked maximum temperature (it does not overheat, it can be wrapped or crossed over safely)
- FAST INSTALLATION: laid in grooved insulation boards, it can be cut or extended at will during installation
- DURABLE: it is mechanically very durable.

The self-regulating, intelligent nVent RAYCHEM T2Red system detects obscured zones (under furniture and carpets) on its own and reduces heating, and rearranging furniture in the future is not a problem. It is suitable for all types of floor coverings. Supplementing the system with aluminum-coated nVent RAYCHEM Reflecta insulation boards, you get even heat distribution and minimal energy consumption, but it requires raising the floor level by 13 mm.
Fixed-resistance ducts and mats are used for ceramic and natural stone floors. Factory-finished, thin (3 mm thick), single-sided powered nVent RAYCHEM QuickNet mats are ideal for renovations and refurbishments.

CONVENIENT ACCESS IN WINTER
Electric heating systems are an effective method of maintaining the surface of sidewalks, driveways and walkways in a condition that ensures trouble-free and safe movement. A properly designed and executed anti-icing system ensures the safety of vehicular and pedestrian traffic, reduces the cost of repairing damage to the pavement caused by freezing water, saves energy and time in clearing ice, and protects the environment.
CONCRETE REINFORCED LOADING RAMPS
In areas with special traffic — parking lots, loading ramps, entrances to underground parking lots and even helicopter landing pads and airports — durable and damage-resistant nVent RAYCHEM EM2-XR self-regulating cables (300 W/m², 90 W/m at 0°C) are used. Thanks to self-regulating technology, these wires maintain the required temperature along the entire length of the heating circuit. They are very safe — they do not overheat even at the point of crossing.

ASPHALT DRIVEWAYS
EM2-MI mineral insulated high-temperature heating cables are the best solution for heating systems laid in hot asphalt. No other heating cable is as resistant to high temperatures and damage during installation. The EM2-MI system, available in kits from 1270 W to 4290 W, can be easily adapted to irregularly shaped surfaces. The factory-terminated heating cables do not require the installation of terminations and cold leads during installation and can be attached to existing reinforcement or spacer strips.
Driveways, sidewalks and stairs made of concrete and covered with paving stones
In this case, we use fixed-resistance conductors and mats. This is the most economical solution, characterized by simplicity and short installation time.
Raychem WinterGard heating mats with a power of 300 W/m² and a width of 60 cm work well for clearing snow from sidewalks and driving lanes. They can be unrolled immediately before concrete is poured. The factory-terminated 30 W/m nVent RAYCHEM WinterGard fixed-resistance heating cables are laid on stairs, complex and irregularly shaped surfaces. The 2-wire cable design means only one cold wire to be connected to the power supply and controller.
PROTECTING PIPES FROM FREEZING
Frozen pipes are a costly problem — when they are exposed to sub-zero temperatures, they break, leading to significant damage and disruption to facilities. Self-regulating nVent RAYCHEM FroStop heating cable or the new halogen-free, low-smoke XL-Trace cables, combined with appropriate thermal insulation, will effectively protect water pipes, hydrant and sprinkler systems from freezing.

PROTECTION OF ROOFS AND GUTTERS AGAINST SNOW AND ICE ACCUMULATION
The complete self-regulating system with electric heating cable FroStop Black, with 28 W/m in snow/ice, 16 W/m in air at 5°C, provides reliable protection against damage in winter conditions. It is possible to fully automate the operation — the nVent RAYCHEM EMDR-10 controller with temperature and humidity sensor turns the system on automatically only under the simultaneous occurrence of certain weather conditions.
